Detection Circuit Wiring

All detection circuits may be wired as "End Of Line" (EOL)
or "Double Pole" (DP). Both methods can be used on the
same equipment.

Double Pole

The DP method requires the following:
The detector alarm and tamper contacts are
l
connected to the zone and tamper terminals
respectively.
The combined alarm and tamper loop resistance
l
must be less than 100 Ohms.
The maximum number of detection devices
l
allowed in a circuit is ten.
Normally open devices such as exit terminator
l
buttons are connected across the zone terminals
and then must be programmed with the "Invert"
attribute.
If the detection circuit is not used links can be fitted
l
across the zone and tamper loops or programmed
as "Not Used".

End Of Line

The EOL method requires the following:
The detector alarm contacts must have a 4K7
l
shunt resistor fitted.
A 2K2 End of Line (EOL) resistor must be fitted at the
l
point in the circuit furthest from the control panel.
Loop resistance with the EOL resistor shorted must
l
be less than 100 Ohms.
The maximum number of detection devices
l
allowed in a circuit is ten.
Normally open devices such as exit terminator
l
buttons are connected in the same way as

Control Panel Sounder Connections

The following terminals have been provided to allow
connections to an external sounder:
H/O+ This is used to provide a permanent +ve hold
off to external sounders, strobes etc. It is
protected by a 1A fuse (Bell 12V).
H/O - This is used to provide a permanent -ve hold
off to external sounders, strobes etc.
TR - This is the negative tamper return connection
from the external sounder unit.
STB - This is the strobe trigger output which switches
to 0V on alarm and is rated at 500mA.
Normally this output is connected to the
strobe -ve , the strobe +ve is connected to
[H/O+].
TRG - This is the bell trigger output which switches to
0V on alarm and is rated at 500mA. This output
can be programmed for SAB or SCB
operation, and operates as follows:
SAB - Switches to 0V on alarm and provides a
maximum of 500mA.
SCB - Provides a negative hold off (500mA),
which is removed on alarm.
